  • Title: Doppler derivation of complete pulmonary artery pressure curves in patent ductus arteriosus.
    Author: Becker TE, Ensing GJ, Darragh RK, Caldwell RL.
    Journal: Am J Cardiol; 1996 Nov 01; 78(9):1066-9. PubMed ID: 8916495.
    Abstract:
    Doppler echocardiography can be used in patients with a patent ductus arteriosus to generate complete pulmonary artery pressure curves. This technique provides a dynamic evaluation of changes in pulmonary artery pressures throughout the cardiac cycle and provides more hemodynamic information than single-point Doppler velocity methods of estimating pulmonary artery pressures.
